Image Handler 4 (for v1.5.x) Support Thread

@Metaus

There is a php error occurring at some point for some reason.

First, have a look at the debug files in the cache folder and see if you can see what the problem is.

Secondly, post again and include that information and the site URL. Without a bit more information people are going to struggle to help you. You probably just need to post the contents of the most recent debug message.

Thanks for the quick reply,
here is the info from the debug file:

[09-Jul-2012 13:04:23 UTC] PHP Fatal error: 1062uplicate entry 'ZEN_LIGHTBOX_PREV_NEXT' for key 'unq_config_key_zen' :: INSERT INTO zen_configuration (configuration_id, configuration_title, configuration_key, configuration_value, configuration_description, configuration_group_id, sort_order, last_modified, date_added, use_function, set_function) VALUES (NULL, 'Always show Prev / Next', 'ZEN_LIGHTBOX_PREV_NEXT', 'false', '<br />If true, the lightbox will always show Previous & Next buttons when using additional images. NOTE: This setting will be overwritten automatically when Close on Image Click is set to TRUE.<br /><br /><b>Default: false</b>', @cgi, 112, NOW(), NOW(), NULL, 'zen_cfg_select_option(array(''true'', ''false''), '); in public_html/includes/classes/db/mysql/query_factory.php on line 101

it seems as though this error is relating toe zen lightbox however? I recently just installed the current version of that (following my upgrade to ZC 1.5).

furthermore, the website is: www.calluccimenswear.com.au
Currently I have 'IH resize images' set to 'no' so you will be able to see the products when you click on the various categories (which have products in them)

thanks kindly

One other possibility - you have images too large. That will let the page show but the product list disappears. Go check the sizes - if they are over 100kb, that might be the problem.

@delia

Yes images are definitely over 100kb (quite large approx 1mb). However I never had this issue previously with zc 1.3.9h and IH 3??
I tested this theory by uploading a product image that was only 41kb (selected overwrite previous image) however products still not showing under their respective categories when 'IH resize images' is set to 'yes'.

any further ideas?
I really appreciate everyones 2 cents on this issue.

Cheers

It only takes one large image to take down the product listing. I don't know why this happens but it does. Obviously, it cannot handle resizeing large images and if you've put up images around 1 meg, you really need to resize and optimize your images before even thinking about putting them on any site at any time. I use the rule of thumb of 500px max width and 500px max height. You don't need anything larger normally. Using higher resolution or larger images does not improve the image quality as the web only sees 72dpi. You can have a jpeg at 300dpi - but that means the px sizes are that over 3 times larger.

@Metaus

What delia says may well be true. And may well be causing the problems on the front end. Personally, I go for about 800 by 800 as a top limit, because a lot of clients like to have a zoom feature these days, but you can decide what size suits you.

BUT you definitely have an error on the install of lightbox and IH. So, you need to read carefully the Read Me for IH and pay particular attention to the section covering installing lightbox and IH.

[metaus]

Ok everything seems to be working. Huge thank you to the both of you for contributing and helping out!
I simply resized the images to approx 750x500 pixels (which reduced the sizes to approx 50-80kb each). Everything is working as it should, including lightbox.
I do have one problem on the specials page of my site however: http://calluccimenswear.com.au/index...page=page&id=2

as you will see there is random writing up the top of the page. I attempted to locate this page and its locaiton of the writing however to no avail.
Would anyone have any ideas?

thank you once again!

This issue is not related to support for Image Handler. Looks like an error related to the Zen Lightbox add-on.. Please create a post in the Zen Lightbox support thread to get assistance on this..

I used the thread's search function but didn't see my problem.

I'm aware of the product red/green on/off bug caused by IH4 and applied the fix for that.

However, I am experiencing the same problem with my Specials in admin: red/green on/off button does not work.

Fresh 1.5 ZC install with IH4 yesterday on my main site: prommart com

I have another fresh 1.5 cart without IH4 and the Specials on/off button works there, so I suspect IH4 for now.

Anyone experienced the problem with the Specials button and know of the fix? Thanks.

EDIT: Just noticed the same Specials button problem on my sister's 1.5 site with IH4

Similar issue.. different cause.. The issue with the product red/green on/off required a fix to a file that IH4 modifies (admin/includes/modules/category_product_listing.php).. The issue you are experiencing with specials is NOT caused by IH4 as IH4 makes NO modifications to the specials listing at all..
